Constantly bugs me to upgrade to the paid version. ads that get in the way of the words I'm looking up and that are often difficult to close. bugs such as not selecting the definition I'm tapping or ads refusing to close despite having the option. and then getting told to upgrade again. extra star for the fact that it is a dictionary with words and definitions. but come on, even the *pronunciations* are pay walled. be so for real.

Hello. The free version includes full dictionary access with ads. Premium removes ads and unlocks offline use, audio pronunciations, a thesaurus, examples, and more. We’re always working to improve and appreciate your input.

I paid for a subscription because I genuinely like the Oxford Dictionary. Unfortunately this app sucks. A lot of words that I would regard as very basic do not come up when you search. Despite having the premium subscription there is no way to back up & transfer any of your saved favorites to another device. The "help" section for mobi systems is completely useless, and checking the forums anytime a user asks a question all they get is a canned response "we're discussing it with our team"

I really don't understand the point of this app tbh. So, you can either use the free version, and get blasted with an ad you can't skip for 10 seconds as soon as you open it, or pay $3/month to be able to use it without ads. But why would I do either when I can just use my browser to search it and get no ads and pay no money? I'm going to do that now.

Hello Nico Landrum. To maintain a completely free-to-use app while offering advanced paid functionalities, we rely on two support methods: ads and the cost of the paid version. If ads are bothersome, please consider upgrading to Premium for an ad-free experience and access to the full feature set.
